Lincoln Center in New York says it will offer a live stream from a weekend memorial concert for folk singer and activist Pete Seeger and his wife Toshi.

The free concert will be held July 20 at Lincoln Center's Damrosch Park. It will feature artists and speakers who had a close personal relationship with the Seegers. They include Judy Collins, Harry Belafonte, Dar Williams, Peter Yarrow, Holly Near and Tom Chapin.

Lincoln Center notes that Seeger loved to lead singalongs. In that spirit, it's inviting audiences to take part in a global online singalong.

A song will be selected later this week and lyrics will be available on-screen.

Audience members also will be able to share video of their renditions.
